The present invention relates to journal box lubricators or oilers andthe primary object of the invention is to provide an improved locomotivejournal oiler which will assure constant lubri- 5 cation of the journalat all times.

A further object of the invention is to provide an improved driving boxcellar which may readily be substituted for the present types ofcellars, and one wherein loss of oil is prevented.

A further object resides in the improved means for conveying the oil tothe journal and spreading the oil therealong for proper lubrication.

A further object of the invention resides in the provision of means forproperly lubricating the oil feeding means employed for conveying theoil to the journal.

A further object is to provide an improved journal oiler which while notlimited to such use, is especially well adapted for use in connectionwith locomotive driving boxes.

A still further object is to provide a driving box cellar which may bereadily filled with oil without removal from the box, and also embodyingmeans for gauging the amount of oil in the cellar.

A still further object resides in the provision of a self-locking keeperbolt to removably retain the journal oiler in the box.

Other objects and advantages of the invention 30 will be apparent fromthe following detailed description, taken in connection with theaccompanying drawing, forming a part of this specification and in whichdrawing:

Figure 5 is a fragmentary sectional view of a portion of the lubricatingmeans shown removed from-the oil container.

Figure 6 is an enlarged detail view of one end portion of a cellar orkeeper bolt.

In the drawing and wherein like reference characters designatecorresponding parts thruout the several views, the letter A designates adriving box of conventional construction provided with the improved.journal oiler or cellar B. The letter C designates a driving axlejournal mounted in the box A and on the outer ends of which the drivingwheels are mounted as at D.

The driving box A is of usual construction embodying the depending sidearms 5 between the upper ends of which is mounted the bearing 6 5retained in place by the holding plate 1 disposed at the inner end ofthe box.

Referring now to the construction of the oiler or cellar B, the same isadapted to removably fit between the arms 5 beneath the journal C andembodies an oil container or cellar proper 8 of box-like formationproviding vertical side walls 9, end walls I0 and a bottom wall II. Theend walls I0 have their upper edges of semi-circular shape as shown inFigure 3 for receiving the journal C. Depending from each corner portionof the bottom wall H is an apertured lug l2 and these lugs are adaptedto receive cellar or keeper bolts E for removably supporting the oilerbetween the arms 5. 20

Arranged within the container 8 is a lubricating means for conveying oilto the journal C and this means embodies an open rectangular-shapedframe member l3 having side rails I4 and end rails I5. Secured along itslower edge to the outer side of each side rail [4 is a wiper plate l6formed of spring material and which has a normal tendency to springinwardly at its upper portions as shown in Figure 5. These wiper plates16 extend substantially thruout the length of the side rails 14 and havesecured along their upper edges and at their inner or confronting sides,strips of felt or the like 11 which are normally urged into wipingcontact with the journal 0.

Adapted to be removably supported in the open 35 frame member I3 is anoil feeder or lubricator unit F for conveying oil disposed in thecontainer 8 to the journal C. This unit F comprises a supporting shaftI8 which is adapted to be secured at its ends to the end rails l5 as byscrews or the like l9 passed thru openings 20 in the ends of the shaft.Slidably fitted on the shaft I8 is a substantially semi-circular shapeddip cup 2| having bushings or sleeves 22 extending from opposite sidesthereof which receive the shaft I8. Extending thru the shaft l8 and thesleeves 22 are cotter pins 23 which act to retain the cup andsleeveassembly against rotation on the shaft so that when the shaft is securedby the screws I!) to the end rails 15, the open side of the dip cup 2|will be retained uppermost as shown in Figure 1.

Freely rotatable upon the shaft 18 within the dip cup 2| is an oilfeeding wheel 24 adapted to have rolling contact with the journal C, andthis oiling wheel is preferably provided at its periphery with a roundedgroove forming spaced annular surfaces for contacting the journal. Thewheel 24 rotates in oil within the cup 2 I, the cup having an opening 25in its bottom for admitting oil disposed in the container 8.

Provided at the upper edge and at one end of the cup 2! is a drip catchpan 26 for catching excess oil scraped from the journal in a manner tobe later described. This drip pan.26 as will be observed has its bottomwall'down'wardly inclined toward the cup 2! and'has its side wallsconverging towards the cup whereby the collected oil feeds toward thecup. The wall 2'! of the drip pan preferably extends above the sidewalls of the pan and forms a shield plate for directing oil into thepan. Communicating with opposite sides of the drip pan, at the low pointof the pan, are two oil delivery tubes 28 which extend along ppositesides of the cup 21 for delivering oil collected in the pan to thebearing of the oil feeding wheel ,24. These tubes 28 may open thru thesides of thecup 2i directly above the shaft [8. Owing to the high speedat which the oiling 7 wheel 24 may revolve at certain times, the oil isthrown by centrifugal action to the periphery of the wheel and away fromits bearing. The delivery tubes 23 willinsure lubrication of the oilingwheel shaft and allow for a lower oil level being maintainedin the oilcontainer 8.

Acting between each corner portion of the open frame member I3 and'thebottom wall ll of the oil container 8, is a coil spring 29 whichnormally urges the frame member upwardly and the oiling wheel 24 into.rolling contact with the journal C.

Arranged at each end of the oil container 8, is an inner end wall orplate 30 disposed inwardly of the end walls 10, and an outer end wall orplate 3| disposed outwardly of the end walls l0 whereby these plates 33and 3! have vertical telescoping relation to the end walls 10. The upperedges of the plates 30 and 3l are of semi-circular shape as shown inFigure 3 for receiving the journal C. Secured to the inner side of eachinner end plate 30 about the upper edge thereof is a felt strip 32,while secured between the plates 30 and 3| about the upper edges thereofis a second felt strip 33. These felt strips 32 and 33 are secured tothe plates by rivets or the like 34 which also serve as means forsecuring the plates 30 and 3| together at their arcuate upper edges. Aswill be observed in Figure 2, the felt strips 33 act as spacers for theend plates 30 and 3| so that the end walls I!) of the oil container mayextend between the plates. The inner end plates 30 are provided adjacenteach end with vertical slots 35 which receive pins 36 projecting from.the end rails l whereby the end plates may move vertically with respectto the frame l3. Secured to the innerside of each inner end plate 30,adjacent to theside edges thereof, are angle brackets 31 against theunder sides of which coil springs 38 act in a manner to normally urgethe connected end plates 30 and 3! upwardly and the felt strips 32 and33 into contact with thejournal C. The lower ends of these coil springs.38 bear upon the end rails l5 of the frame member I3.

Pivotally mounted within the frame member I3 is a pair of U-shapedscrapers 40 each embodying a scraper bar 4| extending parallel to theoiling wheel shaft l8 and arms 42 pivotally mounted at.

their-lower ends as at 43 to the end rails I5. I The lower ends of thearms 42 below the pivots 43, are provided with offsets 44 which areoffset towards the side'rails l4 and act as stops for limiting swingingmovement of the scrapers toward one another. Connecting the arms 42 ateach end of the scrapers 4D is a coil spring 45 and these springs act toretain the scraper bars M in contact with the journal C. When the framemember I3 is removed from the oil container 8, the oilsets 44 willcontact the side rails I4 as shown in Figure 5 and limit inward swingingof the scrapers by the springs 45. The scrapers 40 not only act toprevent excess feeding of oil to the journal, but also as means forspreading the oil along the journal.

The oil container 8 is provided at one end wall If] with a filler spout46 in which is disposed a float gauge 41 for gauging the oil level inthe container 8. As will be observed in Figure 2, the combined oil gaugeand filler is disposed at the inner end of the driving box.

Referring now to the construction of the cellar or keeper bolts E, thesame are of a self-locking type and serve to removably secure the oileror celler B in position in the driving box A. The bolt E embodies ashank 48 having a crank 49 at; one end and having its opposite end screwthreaded as at 50. The threaded end 50 is longitudinally slotted as at5| and pivotally mounted in this slot is a key 52 which, when the shank48 is in a horizontal position, may swing by. gravity to a verticalposition transversely of the shank as shown in Figures 1 and 6. The key52 when disposed longitudinally in the slot 5| lies inwardly of thescrew threads 50, and one end of the key is formed at an angle forengaging the angular inner end of the slot 5| whereby the key may beretained longitudinally in the slot during placing and removal of thekeeper bolt. The side arms 5 of the driving box A are provided at theirlower ends with lugs 5' which are apertured to align with the aperturesin the lugs [2. The apertures in the lugs 5' of one side arm 5 ispreferably threaded for receiving the threaded end 50 of the keeperbolt. When the threaded end 50 projects so that the key 52 clears thelugs 5, the key will swing by gravity to the position shown in Figure land thus retain the bolt in position. As will also be observed in Figure1, the crank 49 and the key 52 both hang downwardly when the bolt is inuse.

With the container 8 filled with oil tothe desired level, the oil willpass into the dip cup 2| thru the opening 25 where it will be picked upby the oiling wheel 24 and transferred from the periphery of the wheelto the journal C. With the journal rotating in the direction of thearrow shown in Figure 1, the surplus oil will be scraped from thesurface of the journal and allowed to drop into the drip catch pan 26and from which this oil is delivered to the bearing of the oiling wheelthru the tubes 28. Since the reversed or backward travel of locomotivesis limited to low mileage, the drip catch pan need only be provided atone end of the dip cup for functioning during forward travel of thelocomotive.

As will be observed, the lubricator unit F is of simple construction,and by removing the screws {9, the entire unit may be removed from thecon-' tainer. By removing the cotter pins 23 the shaft l8 and oilingwheel 24 may easily be removed from the bushings 22 and the dip cup 2|for examination or replacement of parts.

While the oiler has been shown and described for use in connection withlocomotive driving boxes, it will readily be seenthat with slightmodifications to the shape of the oil container 8, the oiler may beassociated with engine truck boxes.
